Subject: November 2012 Sediment Sampling Event
New Bedford Harbor Superfund Site
Operable Unit #3 (OU3) Pilot Underwater Sediment Cap
Dear Mr. Hugh,
This FINAL Technical Memorandum presents a summary of the
sediment monitoring
activities conducted at the Operable Unit #3 (OU3) pilot
underwater sediment cap in New
Bedford, Massachusetts during the 2012 monitoring period. The
2012 monitoring study
is a continuation of a multi-year program developed to sample 17
sediment stations
located within, and adjacent to, the sediment cap.
The OU#3 cap sample collection effort was performed as part of
the 2012 Environmental
Monitoring, Sampling, and Analysis of the New Bedford Superfund
Site Task Order
(TO-0010-07).
Introduction
The pilot underwater cap in Operable Unit #3 (OU#3) is located
south of the hurricane
barrier along the western shoreline of New Bedford’s outer
harbor (Figure 1).
Construction of the 19-acre cap was completed in 2005, using
clean sand and gravel from
a Port of New Bedford navigational Confined Aquatic Disposal
(CAD) cell, and is
adjacent to a proposed winter flounder mitigation area. The
pilot cap covers
polychlorinated biphenyl (PCB)-contaminated sediments just
offshore of the Cornell-
Dubilier Electronics (CDE) facility.
Post-cap monitoring since 2005 has included bathymetric surveys
to determine cap
thickness and grab samples to determine PCB concentrations in
surface sediment (top 0.1
feet). Monitoring has been done annually since the cap was
placed, with exception of
2009 and 2011. Prior to the November 2012 sediment monitoring
event, Woods Hole
Group (WHG) previously completed a sediment grab survey of the
OU#3 cap in 2010. A
bathymetric survey of the OU#3 cap was performed by a Jacobs
Engineering
subcontractor on October 24-25, 2012 at the request of the
USACE-NAE. The
bathymetric survey was performed as part of the annual
monitoring of cap thickness
(Woods Hole Group, 2012a).

Sediment Grab Sampling
Sediment sample stations selected for the 2012 monitoring event
were chosen based on
three objectives: 1) to reoccupy previously sampled sites within
the cap; 2) to fill spatial
gaps in data coverage; and 3) to collect samples in an area
adjacent to the cap designated
for winter flounder habitat mitigation. In total, twenty-five
(25) stations were considered
for sample collection, but at the request of the USACE-NAE these
stations were
prioritized to keep the number of sample locations at 17, which
was the number of
samples called for in the scope of work. The eight
lowest-priority stations were left as
backups, but were not sampled during the November 2012
collection event. All station
locations were accepted by the USACE and EPA prior to sampling.
Station IDs were
labeled in the same manner as previous events (OU02 through
OU25). To avoid
confusion between sampling years, the suffix “-12” was appended
to the station IDs to
indicate that the samples were collected during the year
2012.
Due to a strong north wind and ebbing tide, which combined to
push the boat to the
south/southeast, all of the sampling locations in 2012 were
several meters away from
their proposed coordinates. WHG field crew maintained good
communication with the
vessel captain during sampling, who positioned the vessel
upstream and drifted back over
the proposed coordinates. The WHG field crew stored a sample
position in the handheld
GPS once the grab sampler made contact with the bottom, but due
to boat drift the
sampled locations were between 4 and 27 meters away from the
proposed coordinates.
Stations OU4-12 and OU19-12 were the farthest from their
proposed coordinates (26 and
27 meters, respectively), and the field replicate (REP) at
station OU7-12 is 23 meters
away from its field sample. This was brought to the attention of
the USACE Engineering
Technical Lead and USEPA Project Manager prior to sample
analysis to determine if re-
sampling was necessary, but the sampling locations were accepted
and the samples were
analyzed as planned.
Target sampling coordinates are provided in Massachusetts State
Plane Mainland
coordinates (units in feet) and latitude and longitude in Table
1. Actual sampling stations
are plotted in Figure 1 and listed in Table 2.

Surface sediments were collected at each station. Sediment was
collected using a
stainless-steel Van Veen grab sampler. This device consists of a
stainless steel jaw set
into the center of a weighted frame. The jaws are kept open by
tension on the winch
cable during the lowering through the water column. Once the
device hits the bottom the
tension is lost and the jaws close, collecting a sample of the
top 0.5 feet of bottom
sediment. Each grab sample was inspected to ensure the bottom
surface was undisturbed
and representative of the sediment-water interface. All sites
were composed of varying
percentages of sand and silt (silty sand vs. sandy silt) with
occasional gravel, small
cobbles and shells. Several stations required multiple attempts
due to the coarse
composition of the bottom material. Marine vegetation (Ulva
lactuca/sea lettuce) was
common in many grab samples, especially from stations that were
to the west. No
photographs were taken of the sediment, but it was mostly gray
or brown in color based
on firsthand accounts of the WHG field crew, though some samples
contained small
black streaks. Photographing the sediment provides valuable
information and this action
will be included in future sampling events.
Samples were collected using a pre-cleaned stainless steel spoon
to scoop the top 0–2 cm
(approximately 0.1 ft) of the sediment from the grab sampler.
Sediment was spooned
directly into the pre-labeled sample containers, stored on ice
(4°C) in coolers, and
transported to Alpha Analytical Labs (AAL) under chain of
custody. Care was taken not
to collect any sediment that came in contact with the interior
surfaces of the grab sampler.
The grab sampler jaws, stainless steel spoons, and other
equipment that came in contact
with bottom sediment were decontaminated prior to sampling, as
well as in-between
stations. Equipment was rinsed in site water several times for
gross decontamination,
followed by thorough decontamination using a 1% Liquinox
solution, scrubbing with a
hard-bristled brush, and distilled water rinse. More information
regarding
decontamination techniques can be found in the Field Sampling
Plan (Woods Hole
Group, 2012a).
Laboratory Analysis
Sediment samples were submitted to Alpha Analytical Laboratory
(AAL), a
Massachusetts and USACE certified laboratory, for PCB congener
analysis - USEPA
Method 8082. Quality control (QC) of samples was performed by
collecting separate
field replicates (REPs), matrix spike (MS), and matrix spike
duplicate (MSD) samples,
which were submitted for analysis along with the field samples.
The REP was collected
from station OU07 and the MS/MSD samples were collected from
OU12.
WHG submitted one equipment blank (EB), which was collected by
pouring laboratory-
quality deionized water (supplied by AAL) through the
decontaminated grab sampler and
collection equipment (e.g., stainless steel spoons). Analyzing
this sample for NOAA-18
PCB congeners verifies if decontamination methods were
adequate.
All samples were received at the laboratory intact, properly
preserved, and within
temperature acceptance criteria. Information and the Chain of
Custody documents are

as well as electronic
attachments on the accompanying CD.
Results
This monitoring effort analyzed and reported the sum of NOAA-18
congeners, which are
presented in Table 3. The sum of congeners in each of the 2012
samples is all less than 4
mg/kg: samples within the pilot cap range from 0.04 to 3.11
mg/kg with an average of
0.56 mg/kg (excludes three stations located outside the cap
area). Samples from stations
within the proposed flounder mitigation area (OU18, OU21, OU23),
had concentrations
of 2.02, 2.19, and 1.49 mg/kg, respectively. Results from 2012
are much lower than
those in pre-cap samples, which had an average PCB concentration
of approximately 32
ppm in the top foot of sediment (Dickerson, 2007). Caution
should be used when
comparing historical PCB concentrations to 2012 results from the
same station due to
difficulties reoccupying previous sample locations. Also, sample
matrix heterogeneity
can influence PCB congener concentrations greatly, even for
samples that are located just
feet apart.
Areas A and B (Figure 1) are locations on the pilot cap that are
less thick than average.
There were three samples within Area A; sum of NOAA-18 congeners
was 0.07 mg/kg
for station OU25, 0.20 mg/kg for station OU12, and 0.81 mg/kg
for station OU19. From
Area B, the sum of NOAA-18 congeners from station OU09 was 0.1
mg/kg. Although
these stations were not located in the exact location as
historical stations, these
concentrations were similar to historical results from Areas A
and B acquired from the
New Bedford Harbor Database (Table 4). In Table 4, results from
Area A are indicated
with “(A)”, results from Area B are indicated with “(B)”, and
results shaded gray were
from the proposed winter flounder mitigation area outside the
pilot cap area (Figure 1).
Results from the equipment blank (EB-111512-01) were all
non-detects, indicating that
decontamination procedures were successful.

Data Validation
Data validation was completed by New Environmental Horizons,
Inc. (NEH). Detected
and estimated (J) values were used during the summation of the
NOAA-18 congeners; a
value of zero was used for a non-detect (U) and a non-detect
estimate (UJ) (Woods Hole
Group, 2012b). The full data validation report is available in
Appendix B and on CD
with the electronic data attachments.
Laboratory results were submitted to New Environmental Horizons,
Inc. for EPA Region
I Tier I+ validation of PCB congeners. The intentions of data
validation are: 1) to
determine if the data were generated and reported in accordance
with the Field Sampling
Plan and Quality Assurance Project Plan, New Bedford Harbor
Superfund Site, Operable
Unit (OU1) (Woods Hole Group, 2012a and 2012b); 2) to determine
if the data meet
project data quality objectives for acceptable accuracy,
precision, sensitivity, and
technical usability and; 3) to generate an electronic
deliverable of validated results with
project-specific data validation qualifiers added.
Based on this Tier I+ validation of 18 NOAA PCB congeners, all
results were considered
usable for project decisions based on a comparison to the NBH
OU1 QAPP Addendum
2012 requirements and with the understanding of the potential
uncertainty (bias) in the
qualified results.
The equipment blank had non-detects for all congeners. The
LCS/LCSD recoveries were
acceptable for all 18 NOAA congeners, which indicate acceptable
laboratory accuracy for
the method of analysis in the absence of the site matrix. MS/MSD
accuracy was
acceptable for all 18 NOAA congeners from sample
S-12N-G014-0.0-0.1.
There was one field duplicate (FD) pair reported:
S-12N-G009-0.0-0.1 & S-12N-G009
0.0-0.1-REP. FD precision was unacceptable (RPD > 50%) for
ten of the 18 NOAA
congeners in this FD pair. These ten congener results were
estimated (J) in both FD pair
samples with indeterminate bias due to FD imprecision. These FD
results are an
indication of sample heterogeneity that may affect
representativeness of the 18 NOAA
PCB congeners to the site sediment locations.

INTRODUCTION
Samples were analyzed at Alpha Analytical Laboratories. Upon
receipt, samples were divided
into sample delivery groups (SDGs), which were assigned a unique
7-digit number preceded by
the letter L. One SDG typically describes 20 samples and
consists of three data files. The table
below describes the contents of each SDG file from the OU3 cap
sampling.

Number: TO-0010-07 Report Date: 12/11/12
Case Narrative
The samples were received in accordance with the Chain of
Custody and no significant deviations were encountered during the
preparation
or analysis unless otherwise noted. Sample Receipt, Container
Information, and the Chain of Custody are located at the back of
the report.
Results contained within this report relate only to the samples
submitted under this Alpha Lab Number and meet all of the
requirements of
NELAC, for all NELAC accredited parameters. The data presented
in this report is organized by parameter (i.e. VOC, SVOC, etc.).
Sample
specific Quality Control data (i.e. Surrogate Spike Recovery) is
reported at the end of the target analyte list for each individual
sample,
followed by the Laboratory Batch Quality Control at the end of
each parameter. If a sample was re-analyzed or re-extracted due to
a
required quality control corrective action and if both sets of
data are reported, the Laboratory ID of the re-analysis or
re-extraction is
designated with an "R" or "RE", respectively. When multiple
Batch Quality Control elements are reported (e.g. more than one
LCS), the
associated samples for each element are noted in the grey shaded
header line of each data table. Any Laboratory Batch, Sample
Specific %
recovery or RPD value that is outside the listed Acceptance
Criteria is bolded in the report. Performance criteria for CAM and
RCP methods
allow for some LCS compound failures to occur and still be
within method compliance. In these instances, the specific failures
are not
narrated but are noted in the associated QC table. This
information is also incorporated in the Data Usability format for
our Data Merger tool
where it can be reviewed along with any associated usability
implications. Soil/sediments, solids and tissues are reported on a
dry weight
basis unless otherwise noted. Definitions of all data qualifiers
and acronyms used in this report are provided in the Glossary
located at the
back of the report.
In reference to questions H (CAM) or 4 (RCP) when "NO" is
checked, the performance criteria for CAM and RCP methods allow for
some
quality control failures to occur and still be within method
compliance. In these instances the specific failure is not narrated
but noted in the
associated QC table. The information is also incorporated in the
Data Usability format of our Data Merger tool where it can be
reviewed
along with any associated usability implications.
Please see the associated ADEx data file for a comparison of
laboratory reporting limits that were achieved with the regulatory
Numerical
Standards requested on the Chain of Custody.
HOLD POLICY
For samples submitted on hold, Alpha's policy is to hold samples
free of charge for 30 days from the date the project is completed.
After 30
days, we will dispose of all samples submitted including those
put on hold unless you have contacted your Client Service
Representative and
made arrangements for Alpha to continue to hold the samples.
Please contact Client Services at 800-624-9220 with any
questions.

Case Narrative (continued)
Sample Receipt
Sediment samples were received intact on November 16, 2012 The
samples were placed in frozen storage
immediately upon receipt. The samples were removed November 27,
2012 and analyzed for initial percent
solids air-dried and then replaced in frozen storage on November
29, 2012. Samples were again removed
from frozen storage on December 5, 2012 when they were removed
to extract samples for PCB Congener
analysis and analyze for air-dried percent solids.
PCB Congeners by GC/ECD
The PCB Congener analysis was performed utilizing dual column
confirmation with the higher of the two values
reported. Technical judgment was employed in the case of an
observed interference. In each case that
interference was observed on one column, the value from the
opposite column was reported regardless of
whether it was the higher or lower value.
The WG575133-2/-3 LCS/LCSD recoveries, associated with
L1221058-19, are below the individual
acceptance criteria for Cl2-BZ#8(26%)/(28%) due to obvious
interference.
Samples L1221058-01, 02, 03, 04, 07, 13, 14, 15, and 17 have
elevated detection limits due to the dilution
required by the elevated concentrations of target compounds in
the sample
I, the undersigned, attest under the pains and penalties of
perjury that, to the best of my knowledge and belief and based upon
my personal inquiry of those responsible for providing the
information contained in this analytical report, such information
is accurate and complete. This certificate of analysis is not
